During a phase change, the heat transferred to a substance is used to break intermolecular forces (latent heat), and thus the temperature of the substance does not change. The opposite also occurs: heat is transferred from a substance during a phase change without a decrease in temperature as intermolecular bonds form.
sublimation
Dry ice undergoes sublimation, an exothermic change, at room temperature.
That depends on what material you are talking about.
this is the dramatic, reversible colour change that occurs when a material is melted or dissolved in a solvent, it is a phase change not a temperature effect despite its name.
the phase change is from solid into gas,and this phase change is called sublimation.

Freezing is the phase change that occurs when a liquidchanges into a solid.
Temperature is constant during a phase change.
sublimation
This depends on the type of sample.
Dry ice undergoes sublimation, an exothermic change, at room temperature.
Each element and compound has its own temperature at which the phase change from liquid to gas (evaporation) occurs. For instance, the evaporation of water occurs at 100oC, whereas the same for (liquid) oxygen is -182.96oC. Some substances sublimate, i.e. that change from solid to gas without going through the liquid state/phase first; e.g. (solid) carbon dioxide.
That depends on what material you are talking about.
As temperature increases in a substance, the component particles become more energetic and eventually a phase change occurs.
Typically, the temperature doesn't change during a phase change.
